You have free reign on the cards you include in your cube, so you can make the answer be yes.
While this is an easy catch-all answer, drafters would be expecting green to do green things. From there, land and ramp gets a bit stronger and it's possible that attempts to bolster the other colors actually help green more. Sure, you
can make your cube do most anything, but it can definitely go too far.
Be sure to be a monster and play nonmatching basic land art in your basic land box.
I didn't think about this, but I guess I'd wanna add a few nonmatchers.
Again, it depends on what you pair it with. E.g.
Plated Seastrider is kind of an ass card, but it defends the ground really well, has two pips for devotion, and encourages looking for late game answers.
Patron Wizard is another card that heavily favors slow decks while juicing up devotion. Wizards even is a creature type you could build around.
Apprentice Wizard is grrreat for Eldrazi builds.
Arcanis the Omnipotent is some sick ass card advantage on a stick.
Serendib Sorcerer holds down the fort.
Suq'Ata Firewalker is a 20 turn clock, enough to get to your Eldrazi.
Thassa's Oracle is a nice, non-aggro devotion pay-off that promises an alternative win condition if you can drag out games long enough. Et cetera.
Again, I don't love the catch-all solution of "change all the other cards and this card will work."
There comes a point of watering down the format so much that the challenge of making Eldrazi work becomes inevitable. If we keeping sliding down that slope, there comes a point where Eldrazi is the dominant deck and other strategies become tier 2, like ROE draft.
Serendib Sorcerer is one I keep going back and forth on and is a good pick for devotion.
If an aggro deck is there, for red and white, I will ignore everything above four mana, including Eldrazi.
I feel the same and think that Wx or Rx Three Tree Eldrazi probably won't come together because of it.
If other colors have the tools to drag out a game, offering aggro options to those colors effectively lures you into a trap.
I wouldn't say it's a trap. Aggro decks did well in Rav Standard against Wrath, Fetters, Helix, Remand, Loxodon Hierarch, etc.
If it's not a trap, do Eldrazi decks stand a chance?
I swear I made a post about a day where we made two red decks and two green Eldrazi decks out of modified Sealed pools where the pools were separated by color. TLDR is that red beat green like 10-2 or something, but 3-4 of those games were down to the wire. A couple more topdecked lands for red and it easily could have been 8-4. This was in the first version of the cube which was pretty damn fast.
There's also
this post where I made two decks played both red and green to success in the same day.
I think red vs Eldrazi should be red favored or there's nothing to police the Eldrazi, but I'd like the Eldrazi deck to stand a chance.
I don't think it's too far off.
With eldrazi spawns/scions I think Three Tree City is neat even if Green uses them as well. It’s a feature of the format. If you can get other types in there too then multiples makes sense.
Yeah. I was thinking Three Tree does fine if you play a couple spawners. I was also thinking Elves could be a faster and more vulnerable ramp deck compared to using rocks and lands to ramp.
For Ux, untapping permanents seems like an easy way to abuse the lands and artifacts, giving the color a unique twist on ramp.
True. We keep touching on that and we keep having too few interesting things to target. These lands are exactly what you'd want. But you know what color's best at untapping lands? Green.
Coffers is cool, I dig it and Black is good at heavy devotion.
Yeah. I'm pretty convinced on some Coffers, Ghasts, and removal as a deck.
For Wx, devotion seems like the way to go for slower decks that might have some Oblivion Ring style of removal.
I was also thinking
Stasis Snare and similar could be a way to push white devoted.
But if you are aggressive, you don’t care about fatties, so not sure.
That's kinda where I landed on Three Tree, but still thought it was worth discussing. Maybe Elementals, Elves, and Eldrazi can be the Three E of Three Tree.
I think Three Tree is decent in aggro even if there's no Goblin Eldrazi deck.
I thought about this, but would you bin your whole board of 2/2s for a titan? Feels like the Three Tree problem where you're better off attacking.
This could work, but I feel like Cathodion and Su-Chi are happier in Bx sac and that the red cards, besides Novelist, still primarily encourage attacking.
Enterprising Scallywag small time ramp goblin.
Runaway Steam-Kin not a goblin, definitely a ritual.
So I think goblin ramp has game!
I have these and like the flexibility, but would they make you play ten mana cards in your red go wide deck? Again, I think the red player would rather be attacking with them. Red players are simple creatures, after all.
Conclusion?
Both of you reinforced a lot of what I was thinking. We can try to make R/W play a titan, but they're probably gonna turn the dudes sideways and ignore it. Three Tree City isn't gonna be the answer, but Nykthos has potential.
I think blue can play control into a titan.
I think black Coffers looks promising, but could prove unfun to draft.
Green can obviously get there.
I think white can be a good supporting color with wraths and other removal, but the weenie side of white doesn't want to deal with titans.
I think red can be a good supporting color with removal and treasures, but red mages like the red zone.
It's probably ok that we don't see white or red-based Eldrazi decks.
Bonus thought:
It's possible I need to accept that the Eldrazi are mostly green cards rather than trying to spread them around because they're colorless.
